T all whom it may concern. I 7

Be it known that 1, WILLIAM BAMBER, a subject of the King of Great Britain, and

I resident of Mulvraf Mayfield Road, Sutton, in the county of Surrey, England, have invented certain new and useful Improve ments in Folding Boxes (for which I have filed applications for patents in England dated, respectively, November 2nd, 1921, and

at February th, 1922) of which the followple manner when required for use, and will be strong and rigid so as to protect effectually the article to be enclosed therein. A further object is to provide a box in which the article to be held can be inserted and removed laterally; in the case of an electric lamp bulb this result is attained by making the tip of the bulb engage in a hole in an indented bottom of the box, and by making the socket end of the bulb pass through a lateral slot into and out of engagement with an aperture in the top of the box, this latter being made to take a V-shape when erected. These and other objects are attained in the manner which will appear from the following description. A

The invention is illustrated in the accompanying drawings, wherein:-

Figure 1 shows a fiat blank as cut out from the sheet, before its ends are gummed together. 7

Figure 2 shows the blank with its ends gummed together. I g

Figure 3 shows the box erected and" with its last side flap opened to allow of the insertion of a lamp bulb.

Figure 4; is a perspective view of the box when completely'closed. v

Figure 5 is a plan View of the closedbox, and

Figure 6is a section on the line 6-6 of Figure 5.

Figure 7 shows a collapsed box blank of otherwise securing to a fiapf at the end of a modified type for holding an incandescent mantle. a

Figure 8 is a perspective View of such a box made up and ready for the insertion of the mantle. i Figure 9 is a perspective View of'a suitable fork for holding the mantle ring in the box of Figures 8 and 9. Figures '10, 11 and 12 are views corresponding to Figures 7, 8 and 9 showing another rnodification of the incandescent man t'le box. The length of the blankas seen in Figure 1, comprises a strip of cardboard creased at various points so. as to provide first a sec-. tion a for one side of the box, then a section b for the" top end, then a section, 0 for the other side, and finally a section cl forthe bottom end with a flap 0 for gumming or section a, so that the parts will form' a rectangle. From one side of the section a extends a flap 9 which is formed with a tongue h at its edge for tucking in to the rectangle of the box itself. The third section 0 similarly has a flap 2' with a creased tongue k thereon projecting toward the 0p posite side. The fourth section cl forming the bottom of the box has small lateral projections or tongues Z, and it is creased as at m near each end so that it will fold up along the sides and will provide a raised or indented bottom. The section forming the top of the box when it is intended to hold electric lamp bulbs, is creased transversely as at n so as to fold down in a V-form, while it has a hole cut outat the centre asat'o to ac commodate the base of the lamp and is cut through from this hole outwardly in order to form two tongues p which allow the base of the'lamp to be pushed into'place and removed from the side. A small hole as at g in the middle of the bottom d'of the box receives the tip of the lamp bulb as indicated in dotted lines in Figure 6, for the purpose 190 of holding it centrally, while the inwardly creased top 6 of the box exerts a pressure on the shoulders of the lamp bulb, holding it securely in position in the box. The projecting base of the lamp can be inserted int lamp socket if desired, or placed against terminals for testing the lamp without removing it from the box. The tip of .the bulb, although it projects through the hole at g in the bottom of the box, is within the level of the bottom edges of the box because the box-bottom is raised above the bottom edges by the creasing inwardly as at m at each side, as already explained.

Vhen the blank is laid fia't- 'as in Figure 2 for storing and transit, the top Z) and one side a of the box he over the bottom at and the other side 0, while the flaps g and 71 project at opposite edges. The flaps g and i might be folded inwardsif desired, but this is not generallynecessary. hen the box is to be made up for use, the one side of the box is lifted with respect to the other side so that the blank a, b, a, (Z, forms a parallelogram, and then the bottom at is pressed inwardly to the extent allowed by the creases m and its projecting flaps Z are turned down. The top 6 of the boxis then pressed inwardly at its crease n to a V-form so that the sides a, 0, of the box are parallel, and the flap 2' is brought'up so that its tongue is is inserted against the side a of the box, between it and the gummed flaps e, f, at the base, and inside the inwardly Vd top 5 of the box. The other side flap 9 of the box is left openas in Figure 3, and the box is now ready for receiving the lamp bulb. This can be inserted by putting the point of the lamp bulb in the hole at g in the bottom of the box, and pressing the base of the lamp bulb between the tongues at p at the topv of the box into the central hole at 0 therein. The other flap 9 can then be closed by tucking its tongue h in against the side 0 of the box,and the lamp bulb is then fully enclosed and supportedf I A box made up as above described is very V rigid and is not-at all liable to be distorted by any stresses to which it is subjected in usage. This is mainly due to the indenting of the bottom cl of the box on the lines m, and to the tucking in of the tongues h, 7a, on the flaps between the indented portions of the bottom and the side walls of the box. The flaps Z turned down at the sides of the box-bottom (Z not only serve to insure that it is kept up at the right height so as to leave room for the projecting tip of the lamp, but they also serve the important purpose ofstiffening the bottom. If a lamp of slightly larger dimensions than those for which the box was intended, was inserted in the box, and if the bottom d had notthese turned-down flaps Z at its sides, the bottom would be liable to be creased transversely and'pressed downwards, when thetip might project below the lower edges of thebox sides so that it would be liable to be damaged and the bulb destroyed. With the bottom of the box made as above described however, if the lamp bulb inserted therein is preferably formed in the side of the box as at r where the tongue h of the flap 9 is tucked in (on the side at which the box top Z) is slotted for insertion and removal of the base of the bulb). Anyone desiring to open the box then will naturally do so with his thumb inserted at the notch above referred to, when the box-side 9 will be opened out in the correct position for removing the bulb laterally between the tongues 30.

One feature shown in Figures 1 to '3 has not been referred'to hitherto. It is not essential. to the construction, though it is preferably used in boxes for holding large bulbs, and is advantageous in other cases.

This feature is the provision oft-he tongues 8 on the sides of the respective halves of the box-top b. The tongues s, when turned down as in Figure 3 when the box is erected, serve to strengthen or stiffen the sides a and c of the box the tongues it and 7c are inserted at the top. This increases the securityiand rigidity of the box when closed.

The invention has been describedyabove as applied to a box for electric lamp bulbs, but substantially the same constructionis applicable also for use with incandescent gas mantles. For example, Figures 7 to 9 show one form of box adapted for holdingsuch mantles. The box has only its top 15 shown as being recessed or sunk inwardly from the edges of the box, while its base a is flush with the lower edges of the sides 12, w. The base it then has a tongue 00 which is turned up at the rear of the box as in Figure 8 to stiffen the base and to help in gripping the tongue 2 on the back flap y when closed. The box front .2 has a tongue 3 for engaging against the side e of the box. In order to provide a cover for the base and the feet of the mantle ring, the rear edge of the box top 25 has an extension 4, 5, 6, upon it, of which the part 4 forms a stiffening for the part 6, while 5 forms the cover when its flap6 is tucked down between the front 2 of the box and the interior parts thereof. The mantle ring may be inserted in the recess of the box-top t, with its feet supported by a suitable fork 8, as seenin Figure 9, this fork being slid over the part 25 while the ring 10 carrying the mantle is below part if. Thefork 8 preferably has a turned-up end 9 which occupies the position indicated indotted lines in Figure 8 when the fork is inserted, so that the tongue 6 of the cover 5 actually engages between this end 9 and the box front 2. The carton can be collapsed flat as seen in Figure 7, by reason of the fact that the crease at 7 in the box-top can be folded reversely in Figure 7 as compared with Figure 8, the length folded reversely between crease 7 and the side v making up for the length 11, as seen in Figure 7. The ends of the carton are gummed together at 12, Figure 8.

lhe construction shown in Figures 10 to 12 is similar to that of Figures 7 to 9, except that the top section 25 does not have the extension 4, 5, 6 upon it to form the cover, but is provided instead with a tongue 13 to stiffen it, while the cover section 5 and tongue 6 are now upon'a strip 14 which forms an extension of the base u, and is folded up at the back of the box (Figure 11) before the back flap y is closed and its tongue .2 is tucked Boxes of the character hereinbefore described can be used also for holding other fragile articles and their use is not limited therefore to the purposes above referred to. It will be understood further that although boxes such as are hereinbefore described can be cut out from a single piece and made up by folding and creasing, yet, if preferred, the box can be made of two or more pieces suitably gummed or connected together, and securing the same advantages in regard to rigidity of the box, its ease of opening and gaining access to articles carried therein and so forth. The top of the box is also not necessarily V-shaped when it is designed for holding electric lamp bulbs, but the V-shape has proved most convenient in practice while it enables the length of the top of the box and of the bottom. of the box in the flat blank to be kept the same, while bringing the hole at 0 through which the lamp projects sufficiently far down from the end edges of the box.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A folding box comprising two sides and two ends, one end and one side being adapted to fold upon the other end an the other side when collapsed, flaps extend ing from one edge of each side of the box and adapted to form front and back closures for the same, the ends of the box being of equal length when collapsed, and the one end being creased in such manner that it will fold to a V-shape when erected, while the other end is creased adjacent its sides so that it will form an indented end when erected, the box being held in the erected position by the engagement of tongues forming part of the front and back flaps inside the sides of the box.

2. A folding box comprising two sides and two ends, the one end and one side being.-

fold to' a V-shape When erected, and having an aperture therein and a slot leading into said aperture from one side of the V, while the other end is creased adjacent its sides so that it will form an indented end when erected, the box being held in the erected position by the engagement of tongues forming part of the front and back flaps inside the sides of the box.

3. A folding box having two ends and two sides united so as to fold flat with one end and one side folded upon the other end and the other side, flaps with tongues thereon united with the sides of the box and adapted to form front and back closures therefor, one end of said box being creased nearits sides in suchmanner that when the box is erected the said end must be indented, an aperture being formed in the indented surface, while the other end of said box is creased transversely and is formed with a hole therein and a slot at one side communicating with said hole whereby said end of the box when erected can take a V-shape, the box so formed being particularly adapted for holding electric lamp bulbs which can be inserted and removed laterally.

4,. A folding box adapted to receive electric lamp bulbs, one end of said box being adapted to fold to a V-shape when erected the said end having a hole therein adapted to receive the base of a lamp bulb and having a lateral slot through which said base can be pressed into position, two sides of the box extending from the said end and united with creased joints to the other end of said box, said other end having creases near either side enabling it to be folded inwardly to form an indented end of the box and being formed with a hole adapted to receive the tip of the lamp bulb, flaps adapted to form closures for the back and front of the box, and extensions on the sides of the box ends adapted to be turned down at the sides and to stiffen said box ends when erected for use.
